IMPROVEMENT IN FLV-TRAPS.

Specification forming part of Letters Patent No. 118,852, datedSeptember 12, 1871.

To all whom it may concern:

Be it known that I, LOUIS GRIM, of Fort Branch, Gibson county, Indiana,have invented an Improved Fly-Trap, of which the following is aspecification:

This invention consists in the combination of a vessel in the shape of atruncated cone, open at the top, and having guides at its lower end, inwhich is placed a sliding bottom, above which are notches at the base ofthe cone, in combination with another vessel, also in the shape of atruncated cone, but inverted and secured at its lower end to the outsideof the one first mentioned in such manner as to form a channel annularand V-shapcd, in crosssection, between the two cones, the upper of whichis provided with a glass cover, all for the purpose of trapping flies inthe manner hereinafter set forth.

Referring to the drawing, in which Figure 1 is a top view with the coverremoved, and Fig. 2 a sectional elevation, at is the lower cone; 1), thenotches at the base of the same c, the guides at its lower end; 01, theorifice at its top; e, the sliding bottom; f, the upper cone; g, theannular channel between the two cones; and h,'the glass cover supportedby the upper cone.

Fly-bait, when placed upon the bottom d, allures the insects, which passthrough the notches 11. Having eaten their fill they naturally flyupward toward the light shining through the aperture (I. On striking theglass cover they are thereby dashed downward and fall into the channelg, which should contain water, wherein they may perish.

I claim as my invention- I The cone a having the notches 1), guides c,and orifice d, in combination with the sliding bottom 0, inverted cone farranged so as to form a channel, g, and glass cover h resting solely onthe upper cone, all arranged as specified.

LOUIS GRIM.
